1 b all whom may concern:

Be it known that we, FRANK B. Wim'r- WORTH and LOUIS F. Charisma, bot-h citizens of the United States, residing at Los Ange. ies, in the county oi Los Angeles and State of California, have invented a new and usefu-l Radiator, of which the following is a specification.

' This invention relates to radiators for use in connection with internal combustion engines and to improvements in radiators of the type embodied in our U. S. Patent No;

' 1,138,819, of May 11, 1915, filed January 12,

19 14. The primary object of the invention is to provide a simple and economical radi at'or construction which will provide large I size water tubes and a great amount of ra dieting. surface in a compartivel-y small space, the parts of the radiator being cons'tructed to effectively interlock when assem bled so as to enable an expeditious fastening of the parts and provide a strong durable yet flexible construction. 5

Another object of importance is to provide a radiator which comprises tube units between which are-interposed spacer plates whichinterlock "with the units, and provide large ai-r channels which are transverse to the tubeunits, said units being grooved transversely to receive the spacer plates,

' which plates are corrugated and the corruof the tube plate;

gations engage in the ooves. -The invention consists in certain novel features of construction and combinations,

and arrangement of parts-as will be more Fig. 5 is a fragmentary inside plair vie'w I Fig. 6 is a fragmentary top plan view of to the modified form of radiator construction Fig] is a fragmentary to plan view 0 one of thespacer plates 0 the modified form of radiator;

Fig. 9 is a horizontal sectional view. taken on. line Q-9, of Fig. 6-; and

Fig. 10 is a fragmentary inside elevation of one of the the plates of the modified form.

'In the present embodiment of the invention, tube plates 1. arranged-in pairs to provide water tubes. and spacer plates 2', ar-

ranged between the pairs of tube plates to.

provide transverse air channels are used.

The tube plates are identical as to construction and each has a plurality of transverse substantia-lly Vrshaped corrugations thereon. The inner face of each of the tube plates is flattened on the crests of the cor rugations 3 at points between the ends. of the corrugations, as at 4'. From points near but spaced from the ends ofthe unilattencd p.01" tions of the crests of the corrugations 3, the un'fiattened portions are inclined o1 tapered toward the flattened portions 4. This is done to give as much Width and capacity as possible to the tubes formed by the plates.

The tube plates are nested together so that the convex portions of one plate regis: terswith the concave portions oftheother' plate and are then secured to one another along their longitudinal edges. preferably by soldering.

' The spacer plates 2 illustrated in Fig. 4 is simply a transverse corrugated plate in which the corrugations are preferably substantially V-shaped. In order to provide for the interlocking of the spacer plates with the opposed tube plates between the tubes. as shown in Fig. 2 in'the drawings, the outer face of each of the tube lates is provided with longitudinal preferably substantially V-shaped grooves 5 which are- "for rned. in the crests of the corrugations 1nteilinediate the ends of said crests. The end' portions of the crests which are-free of the grooves are located in the same plane as are the bottoms of the grooves in order that the crests of the corrugated spacer late's' 2 will engage with the crests of 't e plates 1 throughout the entire length of the corrugations. The crests of the spacer plate in interlocking with the grooved crests on the outer faces of the tube plates prevent longi tudinal shifting of the plates relative-to one another and insure a perfect soldering at the engaging points of the tube, and spacer ion spaoel; plates air 1 tubes A and are of il regular contour intetion at}; radiator constructed in accordance with .our invention and illustrates a number ofyt ibe units between which are arranged isracergfnlass. As sho n in the W fit-tub are of a 7? 9 :a maximum us nature and proiatin surface. In of the interlocking o the tube and spacerplates', the metal 1s given a chance to -,bena between the joints where-it is soldered without'causing leakage at the joints. The,

' rovide comp aratively lar passages which, are transverse to t e riorly, thus causing the air to contact all of thigpposed metal faces of the tube plates.

erring to Figs, 6, 7, 8, 9 and where in -"we have illustrated a. modified form of radiator construction, the tube and spacer plates" 6' and 7 are constructed so that the ateralair'passages are hexagonal in cross section instead of diamond shape as in the grooves 12,

preferred form;

The tube platesjhave a pluralit of trans verse corrugations 8 thereon. he mner faces of the tube plates 6 are flattened on the of the corru ations throughout the entire length thereo Centrally of the ends of the flattened crests of the corrugations, theicrests are-inwardly ofiset as at 9. The inwardly offset flattened portion 9 of each corrugation 8 terminates at its ends in inclined'orta ered fiat portions 10 which com- ;municate with the flattened end portions 11 of the crests, said end portions 11 being located in the same "aging points of eac air of tube plates. e lates in the mod' ed form are nested toget er as in the preferred form with the flattened ,faces 9 opposed and en age one another at the flattened ends 1110f e corrugations, the portions 9 and 10 of the corrugations providing substantially wide tortuous passages or waterv channels. The plates are soldered at the ends 11 where they engage with one another and perfect joints are. provided. On the outer faces of the plates 6 in the crests of the corrugations are formed substantially V-shaped grooves 12 which ter-. minatenear the' ends of the crests in flat end portions 13, said portions 13 being'located in the same plane as the bottom of the The spacer plates -7 have a series of transvers'ec'orrugations 14, each of which has a substantially -V-shaped crest ortion 15 formed intermgdiat e its ends an whichterminates at the ends of the: corrugationsin jab flattenedend portions 16 corresponding to the portions 13- on the tube plates 6 and adaptedto engage-said'fiortions 13.- fAfter I the tube plates-havebeen assembled in airs as heretofore described, thesubstantial y V- j sha ed crest portions. 15 are positioned within t .e grooves-'12 and the portions 16 of the spacer plates 7 engage the fiat end portions plane and are the en- 18 of the tube plates, 'as shown clearly in Fig. 9 in the drawings. With the space! plates interlocked in the herinbefore described manner, with the tube plates, s11 ping of the spacer lates' relative to the to e plates is prevents and the soldering of the plates to one another may behad in an earpeditious and reliable manner.

The hereinbefore described modified form is similarto the preferred form relative to the water and air passages. The air pas.- sages in the-modified form are hexagonal and the water passages are tortuous as in the preferred form.

What we con "der the most important feature of our improved radiator is the inter looking arrangement between the spacer and tube plates.

greater flexibility of parts since it permits the metal to'be bent without affecting the I joints 'or causing the plates to shift appreoiably relative to one another.

In practice we have found that the form of our invention illustratedin the drawings and referred to in the above' description as the. preferred embodiment is the most eflicient and practical, yet realizing, that the conditions concurrent withthe adoption of This arrangement gives aour device will necessarily vary, wedesire to emphasize the fact that varlous. minor changes in construction, proportion and arrangenient of parts ma be resorted to when required without sacr' cing any ofthe'advantages of ourinvention as set forth in the ap ended claims.
